Title: Improvements in or relating to compressors, particularly for use with aircraft powerplants
IPC: F02C7/047
Filed: 1947-08-21
Abstract: 629,044. Axial-flow compressors. UNITED AIRCRAFT CORPORATION. Aug. 21, 1947, No. 23178. Convention date, Oct. 30, 1946. [Classes 110(i) and 110(iii)] In an axial flow compressor, lubricating oil from the bearings is circulated through hollow guide blades in front of the first rotor. This serves to cool the oil and to prevent iceing in the compressor inlet. All the guide blades 12, Fig. 1, are hollow and cpen into inner and outer annular ducts 20, 18. Some of the blades are divided internally by partitions 56 to provide outward flow passages 58 for the oil. Oil is taken from a sump 28 by a pump 30 and delivered through a filter 32 to lubricating passages 34, 36, 38 of the bearing 24. Used oil passes through ports 46 and returns to a chamber 50 from which it is drawn by a second pump 52 and delivered to the passages 58 in some of the blades. The oil passes inwards through all the blades and is returned to the sump 28 by pipe 68. In another plant, the compressor shaft has a second bearing up-stream from the rotor and this bearing is supported by hollow streamlined struts which pass through'the annular air inlet duct. The oil from the bearings is passed inwards through the hollow struts and then to the inlet guide blades. The inner and outer ducts communicating with the hollow guide blades are divided by partitions into a number of segments so arranged that the oil passes inwards through some blades, outwards through others and finally inwards through the rest to reach the return to the sump.

Title: Hydrostatic measuring apparatus for ascertaining weights or liquid levels
IPC: G01G5/02
Filed: 1921-09-01
Abstract: 168,892. Hardel, J. A. Sept. 1, 1920, [Convention date]. Hydrostatic apparatus; weighing indirectly the liquid contained in tanks.-Relates to the kind of hydrostatic apparatus for weighing goods, or for ascertaining liquid levels in tanks, wherein a load applied to a float directly or through levers is directly or indirectly balanced by the hydrostatic pressure of a head of liquid. The invention consists in the combination of means for preventing contact between the floating-system and the liquid-containing vessel without using guiding means secured to the liquid-containing vessels, and of means for directly or indirectly balancing the load on the float by a column of the same or of another liquid. In the construction shown in Fig. 3 the weight of the goods in the scale pan G is transmitted by a lever C<1> and shackle T to a float F and the weight is indicated by the liquid column b. The position of the knife-edge bearing on the stirrup T is such that the float remains free from contact with the walls of the containing vessel. The pan G may be supported above the lever C<1> by a jointed parallelogram device. The lever C<1> and shackle T may be dispensed with, the goods being placed on or in the float which is kept out of contact with the walls of the vessel by spherical floats therein. In a modification, Fig. 4, a bell-shaped float is used dipping into mercury and containing oil which is pressed up the indicating tube b according to the pressure, exerted bv the load applied either directly to the float or through the intervention of levers. The lever of the liquid in the tube b may be adjusted by means of a screw projecting into the liquid. The section of the containing vessel A may vary to give unequal divisions on the indicating scale and to give greater accuracy with the smaller weights. In the modification shown in Fig. 6 for ascertaining the height of liquid in a storage tank V (permitting deduction of weight therein) the float dips into mercury, and air is pumped into the float by means of a hand pump v excess air escaping through the liquid in the tank V. Weights are added to the scale pan G connected to the float, until pointers i, i<1> register. The weights in the scale pan afford a measure of the height of the liquid in the vessel V.

Abstract: 1,073,792. Double-acting liquid springs. DOWTY ROTOL Ltd. June 10, 1964 [June 11, 1963], No. 23272/63. Heading F2S. A double-acting liquid spring comprises a cylinder member 10, 11 having a plunger 19 slidable therein. The plunger when in a neutral position forms a part of two liquid-filled chambers 35, 36, one of which increases in volume and the other decreases in volume during movement of the plunger. During the movement the chamber of decreasing volume is connected by a valve means to a source of liquid pressure and the chamber of increasing volume to a low-pressure source. Two spring-loaded bearing bushes 27, 28 may be provided to form a partition in a chamber 12, the bushes being formed with holes 29. The holes 29 in bushes 28, 27 communicate with a non-return valve 52 of a pressurized liquid supply and a highpressure port 41, respectively. The valve means comprises annular grooves 37, 45 and passages 38, 50 in the plunger, the edges of the grooves being tapered as at 39 such that in the neutral position of the plunger the grooves partially co-operate with high-pressure ports 41, 46 and low-pressure ports 42, 47.

Title: Crystallisation process for aluminium sulphate
IPC: C01F7/746
Filed: 1962-06-20
Abstract: Aluminium sulphate is crystallized from an aqueous pregnant liquor containing it by adding the hot liquor at a controlled rate to a small quantity of seed crystals of the aluminium sulphate which have been prepared by rapidly cooling with agitation an aqueous pregnant aluminium sulphate liquor from above its saturation temperature, e.g. 54 DEG  C., to between 7 DEG  and 43 DEG  C. and continuing the agitation for an ageing period of 4 to 24 hrs. 5-20% of the initial liquor may be used to form the seed crystals which are preferably of size 25-100 microns.  The liquor may be filtered prior to crystallization and added at the rate of 5-20 vol. per cent to the seed crystals which are maintained at 26-33 DEG  C. by cooling.  The resultant crystals may be separated from the mother liquor by centrifuging or filtration and washed with 30-50% H2SO4.  The mother liquor and the wash acid may be fortified with fresh concentrated sulphuric acid and recycled to the separation stage.  The crystallization process may be carried out continuously or batch-wise and further seed crystals together with pregnant solution in a ration of 4: 1 to 19: 1 [by weight Al2(SO4)3 : seed crystals] may be added to the seed bed and an equivalent volume of crystal slurry removed simultaneously. The pregnant aluminium sulphate solution may be made by the treatment of alumina with sulphuric acid, e.g. as in Specification 1,013,983, and the product of crystallization may be Al2(SO4)3.16-18H2O.

Abstract: 1337842 FET logic circuits HONEYWELL INFORMATION SYSTEMS ITALIA SpA 19 April 1971 [12 March 1970] 23982/71 Heading H3T A variable-function logic circuit has field effect transistors 1, 2, 3 arranged to perform different logic functions (NAND or NOR) according to whether further F.E.T.'s 5, 6 are made conductive or not by a command signal E. If E holds F.E.T.'s 5, 6 off, then a series path exists from the supply V A  through a load F.E.T. 4 and F.E.T.'s 3, 2, 1 to earth, so that if any of inputs A, B, C is low and its F.E.T. therefore non-conductive, the output E is high (+V A ) and a NAND function performed. If E turns on F.E.T.'s 5, 6, then F.E.T.'s 1, 2, 3 are effectively connected in parallel between U and earth. Thus if any of A, B, C is high to turn on its F.E.T. then output U goes to earth, and a NOR function performed.

An exclusive -OR gate (Fig. 6, not shown) uses four of the Fig. 2 circuits, two of which are biased to act as NAND circuits and two as NOR circuits. Another exclusive-OR gate uses six NAND gates (Fig. 5, not shown). The load F.E.T. bias + V G  is changed in accordance with E, to present the right impedance to the series and to the parallel circuits containing F.E.T.'s 1, 2, 3 in the NOR and NAND circuits respectively.
